Meditation means a lot of different things, but at its heart is a quieting of the mind, which can boost your focus and general health. Audio Dharma offers six free recorded classes that introduce concepts and help you through some early sits.

Instructor Gil Fronsdal is a former Buddhist monk, but his meditation courses are taught as a secular introduction to the posture, breathing, and thinking (or lack thereof) that gets your mind and body into a relaxed state. The first recording, in particular, has Fronsdal and his class sitting through a brief 10-minute meditation, followed by questions from the audience that you'll probably have, too. All six classes are available as free MP3 downloads or for streaming.
